Description

Technical Field

[0001] The present application relates to the technical field of electric push rods, and in particular to a wear-resistant and reinforced electric push rod. Background Art

[0002] An electric linear actuator is an electric drive device that converts the rotational motion of a motor into the linear reciprocating motion of a push rod. It can be used as an executive machine in various simple or complex process flows to achieve remote control, centralized control or automatic control.

[0003] Electric linear actuators are universal auxiliary drive devices that can be widely used in electricity, machinery, metallurgy, transportation, mining, petroleum, chemical industry, lifting, transportation, construction, grain and feed processing and other industries. However, the current electric linear actuators have poor compressive performance during long-term operation. When the telescopic rod moves in the cylinder, the cylinder is prone to compression cracking, which makes it difficult to meet the needs of high-intensity operations. Therefore, in order to solve the above problems, we provide a wear-resistant and reinforced electric linear actuator. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant and reinforced electric push rod to solve the problems raised in the above background technology.

[0005] The present application embodiment adopts the following technical solutions:

[0006] The cam is threadably connected to the chassis and the cam is secured to a position 40 feet tall, the cam being adapted to engage the engagement of the chassis with the chassis on one side and the engagement of the chassis on the other side.

[0007] Preferably, a second bearing is fixedly embedded on the upper surface of the base, an inner ring of the second bearing is fixedly connected to a driving shaft, and an output end of the driving motor is fixedly connected to the top end of the driving shaft.

[0008] Preferably, a driving gear is fixedly mounted on the bottom end of the driving shaft, a transmission gear is fixedly mounted on the bottom end of the wear-resistant screw, and an outer surface of the driving gear is meshed with an outer surface of the transmission gear through a gear belt.

[0009] Preferably, a protective cover is fixedly mounted on the bottom surface of the base, a mounting plate is fixedly connected to the bottom surface of the protective cover, and two groups of mounting holes are formed on the bottom surface of the mounting plate.

[0010] Preferably, a fixing seat is fixedly connected to the outer surface of the cylinder, and a left side surface of the fixing seat is fixedly connected to the outer surface of the driving motor.

[0011] Preferably, a connecting seat is fixedly mounted on the top end of the telescopic rod, and a plurality of connecting holes are formed on the upper surface of the connecting seat.

[0012] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0013] The wear-resistant reinforced electric push rod can enhance the overall compression resistance of the cylinder and the telescopic rod through the multiple reinforcement rings provided on the cylinder and the cooperation with the thickened telescopic rod. The two limit grooves provided on the cylinder and the cooperation with the two limit blocks on the outside of the telescopic rod can make the limit blocks telescopically slide inside the limit grooves to ensure the stable lifting and lowering movement of the telescopic rod inside the cylinder. The copper alloy nut on the outside of the telescopic rod can slide closely with the inner ring of the cylinder to avoid the phenomenon of compression cracking of the cylinder, which can meet the needs of high-intensity operations. The wear-resistant screw and copper alloy nut can have certain wear resistance and reduce the wear of the thread during operation. BRIEF DESCRIPTION OF THE DRAWINGS
